Tutorial about controlling multiple Arduinos via Bluetooth Low Power (BLE) with python multi-threading.
Setting up pip and making HTTP JSON request with python
There are no pull-up resistors, because we can use the internal pull-up of Arduino. pinMode(A0, INPUT_PULLUP); int reading = analogRead(A0); Here, 1k / N are used as the load resistor. Actually (200~1k)/N resistor can be used. (lower resistor -> higher detect range).
Setup: Enable the SSH server from the config menu: sudo raspi-config Setting up WiFi for the Pi: http://raspberrypihq.com/how-to-add-wifi-to-the-raspberry-pi/ In order to connect to the Pi via SSH through router, we have to fix the IP address of the Pi.
